Why I can't write this guide
CVV dumps are stolen payment card records: card numbers, expiry dates, and security codes taken from breached merchants, processors, or skimmers. Selling them is card fraud, and buying or reselling them carries criminal liability in the US under 18 U.S.C. § 1029 and similar laws elsewhere.
A "where to sell CVV dumps" article would function as a directory for that market. I won't write it, in any phrasing or format.
What I can help with instead
- Fraud prevention content for merchants: chargeback patterns, AVS and CVV checks, tokenization, 3-D Secure.
- Content on PCI DSS scope, card data storage rules, and breach response duties.
- Explainer articles on how carding works, written for security teams and consumers.
- Guides to legitimate payment processing, high-risk merchant accounts, and marketplace payout rules.
- Consumer-facing pieces on recognizing card fraud, freezing reports, and disputing charges.
If you are researching the topic for defense
Security researchers and journalists do study these markets. That work is done through law enforcement reporting, threat intelligence vendors, and academic fraud research, not through commercial listings. If that is your goal, name it and I can point you to published research angles.
If you want any of the topics above, tell me which one and I'll write it in full.
